SETTING
NOTE:
If the machine is new and after it is broken in,
the same set length of the spring may
change because of the initial fatigue, etc. of
the spring. Therefore, be sure to make re-
evaluation.
If the standard figure cannot be achieved by
adjusting the spring adjuster and changing
the spring set length, replace the spring with
an optional one and make re-adjustment.
Setting of spring after replacement
After replacement, be sure to adjust the spring
to the set length [sunken length 90 ~ 100 mm
(3.5 ~ 3.9 in)] and set it.
1. Use of soft spring
Set the soft spring for less rebound
damping to compensate for its less
spring load. Run with the rebound
damping adjuster one or two clicks on
the softer side and readjust it to suit
your preference.
2. Use of stiff spring
Set the soft spring for more rebound
damping to compensate for its greater
spring load. Run with the rebound
damping adjuster one or two clicks on
the stiffer side and readjust it to suit
your preference.
Adjusting the rebound damping will be
*
followed more or less by a change in the
compression damping. For correction,
turn the low compression damping
adjuster on the softer side.
